1995 f150 302L efi dual tank. When i turn the ingnition to the on position i hear a click and no fuel pump (obviously truck turns over but no start). Rear tank ....i can hear the pump fine and truck fires up no problem. Fuses have all been checked and are good. Im just learning about my trucks fuel system because ive never had a problem with it before. Before i drop the tank and replace the front fuel pump is there any other diaognostic check i should run? Also iveread thatother peoples rear tank have been flowing into their front tank. Mine so far doesnt seem to be doing that. Why is that. Could it be because the front pump is bad but the check valve is still good? Also is the check valves on each tank or is it inbetween the tanks. Thanks in advance. I crawled underneath the trucks and have heen trying to understand how this particular year trucks fuel system works
